As per SCHEDULE III Para 5, of Central Goods and Services Tax Act ( CGST ) 2017, Sale of Open Land and Completed Building is neither treated as a Supply of GOODS nor a Supply of SERVICES.
Hence, no GST leviable on Sale of open plot and Completed Building.
However, as per SCHEDULE II Para 5 Clause (b), Sale of Under-Construction Building/Advance received at the time of construction of Building would amount to a Supply of SERVICE and hence GST will be levied thereon.
